Abstract: The premise and purpose of "Archaeology of the Actor: characters and heteronyms" is to investigate the art of the actor. Not concerning the technical procedures of his art, but searching the inners of the artist that carries within himself his artistic expression transforming it in something singular. Alongside his trajectory of acting, directing and teaching, the author of this poetic archaeology came to this following affirmation: the actor does not play characters, he expresses heteronyms. To elucidate this affirmation this study leaned over a poetic-archaeologic soil: the actor's body. There he inquired/excavated two sedimentary strata: the sedimentary stratum of creativity and the sedimentary stratum of memory. In a third formation, that we can also name as territory, geography or landscape, by blending the considerations drown out of the two previews strata, the heteronymics images of the actor's work are constructed through an analogy between the concepts of singularity, otherness, individual and collective memory, not distinguishing subject from object, character from actor. This excavation was supported by poets, moviemakers, philosophers and scientists that in their creations and studies revealed the feeling of being multiples. Fernando Pessoa, Walt Whitman, Jorge Luis Borges, William Blake, Fellini, Tarkóvski e Spinoza were the guides of this journey.
